| Outline of Final Research Achievements |
The purpose of this study is to propose a method for measuring lubrication with precisely controlling sliding gaps. We proposed three novel lubrication measurement methods: (1) Micro-device integrating sliding parts and actuators using micromachine technology to realize a parallel-plane sliding system, (2) gap measurement method using ellipsometric microscopy to realize real-time measurement of nano-gaps, and (3) fluorescence correlation spectroscopy to realize measurement of lubricant flow in nano gaps by analyzing the motion of fluorescent single molecules. We have succeeded in experimentally confirming the principle and feasibility of the proposed methods.
